DET-TRONICS X3301 Multispectrum IR Flame Detector
Product Overview
The X3301 is Det-Tronics’ flagship multispectrum infrared flame detector. It uses three IR bands and advanced signal processing to reliably detect hydrocarbon fires while ignoring false alarm sources like arc welding, hot CO₂ emissions, sunlight and artificial lights. It is one of the most installed detectors in high-hazard oil & gas facilities due to its long range and fast response.
